I'm new in programming, so i'm trying to make my own publisher to the topic wich controls the motors of my NXT, so here is the code that i have written.I'm not sure if it is the correct thing that i need to control the motors, but i can't compile it.

#include <nxt_msgs/JointCommand.h>
#include <ros/ros.h>

           template<class M> ros::Publisher ros::NodeHandle::advertise(const     nxt_msgs::JointCommand, uint32_t, bool)

        int main(int argc, char **argv)

        ros::init(argc, argv, "JointCommand");

        ros::NodeHandle n;
        ros::Publisher pub = n.advertise<nxt_msgs::>("JointCommand", 1);
        ros::Rate loop_rate(10);

        int test=1;
        nxt_msgs::JointCommand c;
        c = nxt_msgs::JointCommand();
        test = c.effort;



        return 0;

when i try to make my package it gives me the following error :

/ros_workspace/NXT/src/rc.cpp:6:1: error: expected initializer before ‘int’

The error seems to be caused by the template before int main(). I'm not sure what you're trying to do with that looks like a function prototype without a semicolon. The template also doesn't make sense. If the prototype was valid, you'd also want to add a semicolon at the end to terminate
